Tremor was reported as an adverse effect of lithium in 12 of 22 men and 10 of 38 women who had taken it for at least 1 year (108). In an open study, there was full remission of lithium tremor in four of five patients treated with vitamin B6 (213).

In patients taking lithium, high coffee consumption and caffeine withdrawal have been associated with an increase in lithium tremors (Grandjean and Aubry 2009 Mester et al. 1995). A series of case reports and a related small trial indicated that coffee may inhibit intestinal absorption of thyroxine (T4) (Benvenga et al. 2008). 

Tremor A review of lithium-associated tremor examined 64 articles [83 " ]. Lithium tremor occurs in nearly a tiiird of patients. It can occur at any time during lithium treatment. It is related to lithium levels, and is usually not progressive. It is usually limited to die upper extremihes, it occurs at rest and worsens with activity. Consequently, dose reduction is helpful. Beta blockers have been studied in 12 randomized trials. Propranolol at 60-320mg daily is the most commonly used treatment for lithium-associated tremor but nadolol (20-80mg/day), metoprolol (200-400mg/day), and practolol (120 mg/day) have also been used. Gabapentin and primidone have also been recommended [83 ].

Treatment of Manic—Depressive Illness. Siace the 1960s, lithium carbonate [10377-37-4] and other lithium salts have represented the standard treatment of mild-to-moderate manic-depressive disorders (175). It is effective ia about 60—80% of all acute manic episodes within one to three weeks of adrninistration. Lithium ions can reduce the frequency of manic or depressive episodes ia bipolar patients providing a mood-stabilising effect. Patients ate maintained on low, stabilising doses of lithium salts indefinitely as a prophylaxis. However, the therapeutic iadex is low, thus requiring monitoring of semm concentration. Adverse effects iaclude tremor, diarrhea, problems with eyes (adaptation to darkness), hypothyroidism, and cardiac problems (bradycardia—tachycardia syndrome). 

Lithium carbonate is rapidly absorbed after oral administration. The most common adverse reactions include tremors, nausea, vomiting, thirst, and polyuria Toxic reactions may be seen when serum lithium levels are greater than 1.5 mEq/L (Table 32-1). Because some of these toxic reactions are potentially serious, lithium blood levels are usually obtained during therapy, and the dosage of lithium is adjusted according to the results. 

Remember to take lithium with food or immediately after meals to avoid stomach upset. Drink at least 10 large glasses of fluid each day and add extra salt to food. Prolonged exposure to the sun may lead to dehydration. If any of the following occurs, do not take the next dose and immediately notify the primary health care provider diarrhea, vomiting, fever, tremors, drowsiness, lack of muscle coordination, or muscle weakness. 

Following initial assessment, including evaluation of potential suicidality, support systems, and need for inpatient versus outpatient treatment, MW was hospitalized briefly, then followed in the community on medication along with psychotherapy. She has abstained from illicit substances and has returned to her job. She has responded well to treatment with sustained-release lithium carbonate 900 mg once daily at bedtime with a snack. Steady-state 12-hour serum lithium concentrations have stabilized at 0.9 mEq/L (0.9 mmol/L). She now returns to clinic for routine followup. She has tolerated the lithium except for a mild tremor and a gain of 7 pounds (3.2 kg). She is willing to accept these side effects for now, but asks about how long she must take medication since she is now feeling well. 

Lithium augmentation of antidepressants, carbamazepine, lamotrigine, and valproate can improve response, but it may increase the risk of sedation, weight gain, GI complaints, and tremor. 

Augmenting antidepressants with lithium has repeatedly been shown to be effective. But lithium is a difficult medication to take. It is very dangerous in overdose and can quickly reach toxic levels due to fluid loss from diarrhea, profuse sweating, or high fevers. Even at treatment levels, lithium can produce unpleasant side effects such as dizziness, frequent urination, and tremors. Despite all its problems, lithium...

Outside its therapeutic range, lithium has a wide range of undesirable effects. Nervous system-related effects include tremor, difficulty walking, seizures, slurred speech, and mental confusion. In addition there can be cardiovascular effects, nausea, vomiting, and kidney damage. 

A lithium serum concentration of 1.5-2.0 mEq/L may produce vomifing, diarrhea, drowsiness, confusion, incoordinafion, coarse hand tremor, muscle twitching, and T-wave depression on ECG.

Lithium salts are used in the treatment of bipolar affective disorder (i.e., manic depression) and occasionally in mania (but its slow onset of action is somewhat of a disadvantage in this case). Its mechanism of action is still open to debate, but lithium has effects on brain monoamines, on neuronal transmembrane sodium flux, and on cellular phosphatidylinositides related to second messenger systems. Lithium is administered in two salt forms, lithium carbonate (8.98) and lithium citrate (8.99). Side effects are common and include diarrhea, kidney failure, and drowsiness with tremor.

SSRIs reduce dopamine cell firing in the substantia nigra through their effects on serotonin input to this nucleus. The net result is that they can cause generally mild extrapyramidal side effects (EPS) (500). The most common are restlessness and tremors. The same mechanism is probably responsible for their interaction with other agents that affect central motor systems. Thus, the SSRIs can potentiate the tremor seen with lithium, as well as EPS caused by antipsychotics, bupropion, and psychostimulants (376, 500).
